64 bit DMA on RTEMS

[feng1 at bnl.gov (Kate Feng)]

Hi,

   Does RTEMS compiler truly support "64 bit DMA operation"
if the H/W (e.g. processor & data bus)  supports 64 bit data ?
What I meant is that the compiler will not chop down the
64 bit data into two of 32 bit ones.  Please confirm.

   Regards,
